Hi XXXXXXX Thanks for writing in.From your history of having your tongue initial half is red, it seems that this might be due to touching of initial part of cigarette to your tongue which might be causing irritation and resulted redness over that part of the tongue.It is also possible that the inhaled smoke gives maximum irritation to the starting part of the tongue.Stop smoking for few days and observe the effect.If you feel better then it is confirmed that redness is due to smoking. Also, take Tablet Becosules 1 tablet once daily and Tablet Folvite 1 tablet once daily for 2 weeks. Eat plenty of fruits and vegetables as well. Hope, I answered your query.If you have further query or clarification, please ask.I will be happy to help.Wish you good health.
